Title: Focus coil driving device
Inventor: TSUKAHARA MASAHISA
IPC: H04N3/26
Filed: 1991-06-04
Abstract: PURPOSE:To improve the focus performance of the entire screen by providing the focus coil driving device with low power consumption obtaining the accurate focus current. CONSTITUTION:A pulse modulation/demodulation circuit 6 compares a carrier signal generated from a carrier signal generator 7 with a signal to be modulated to output a pulse width modulation signal. A switching amplifier 1 composed of three switch circuits for the positive power source, negative power source, and a GND performs switching operation based on the pulse width demodulation signal. The current of the focus coil 2 is detected as a voltage signal by a serially connected current detection resistor 3, and an error detection amplifier 4 amplifies the difference with the focus reference signal to output the error signal. Thus, the focus current with less distortion can be obtained since the output of the switching amplifier takes three values.

Title: Refrigerator
Inventor: KARAKAMI TOSHIO
IPC: F25B1/00
Filed: 1988-06-01
Abstract: PURPOSE:To perform an operation of a refrigerator with no regulation by using a stationary expansion valve as an expansion valve, providing a heater in an accumulator, applying an input signal to the heater by a temperature regulator, and further applying a control command of the regulator by a signal from a refrigerant temperature detector of a refrigerating cycle. CONSTITUTION:The opening of an expansion valve 3 is secured to a maximum load, and the interior of an evaporator 4 is sufficiently cooled. If a load is reduced, a heater 9 of a refrigerant return line is turned ON. If the opening of the valve 3 is secured to that corresponding to the maximum load, the interior of the evaporator 4 is always held at a predetermined cooling temperature. If the load is decreased in this state, a large quantity of refrigerant liquid is returned to a compressor 1. In this case, the refrigerant liquid is temporarily accumulated in an accumulator 6 immediately before the refrigerant is returned to the compressor 1. The heater 9 is turned ON in this state to return the liquid refrigerant to the compressor 1 as gas refrigerant. Thus, it can prevent the damage accident of liquid compression due to the return of the liquid of the compressor 1. If the load is increased, it can be coped by a manual valve, and the regulation of a refrigerator is not required.

Abstract: PURPOSE:To prevent an induction generator from generating self-excited in outage of power source, by interposing a three-phase three-winding transformer between a three-phase induction generator and the power source system. CONSTITUTION:The primary winding 2 of a three-phase three-winding transformer 1 is connected to the power source, the secondary winding 3 to the load and the tertiary winding 4 to an induction generator 6 through a breaker 5 respectively.

Then, the current IU of the U-phase of the power source side continues flowing through a diode D4, a thyristor S4, a capacitor C, the thyristor S3, the thyristor S1 and the GTO-GY. The IU starts reducing from when the charging voltage of the capacitor C becomes equal to the voltage VUC between the power sources U and V, and the IGV increases. At this time, the GTO-GV fires. The load current IL is commutated to the GTO-GU, and the current IL is circulated through the GTO-GY, GV.

Title: Memory protecting circuit
Inventor: MURAI MASAO
IPC: G06F21/62
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the destruction of a user program and the runaway of a computer by securing such a constitution where an R-S flip-flop is reset in a RAM working area of a CPU and a gate set on the route of the RAM write signal is closed for inhibition of the writing actions to the RAM. CONSTITUTION:In a RAM execution area of a CPU 1, a RAM selection signal 7 is transmitted from an address decoder 5 and an AND gate 11 opens at the time point when an instruction fetch timing signal 9 is transmitted. The output of the gate 11 resets an R-S flip-flop 12. As a result, an AND gate 13 is never opens and no write permission signal 14 is transmitted even though a write signal 10 is transmitted from the CPU 1. Thus the writing actions are inhibited to a RAM 3. Thus it is possible to prevent the destruction of a user program and the runaway of a computer that are caused by a fact that the user program itself written into the RAM 3 is rewritten due to a bug of the user program during execution of this program.
